Els alumnes de 6\u00e8 continuen treballant i resolent els reptes de la Missi\u00f3 Alba utilitzant el seu dossier, fent experiments i aprenent mitjan\u00e7ant el m\u00e8tode cient\u00edfic!!<\/p>\n

En aquest repte del LAB3: “Captura la imatge” hem descobert\u00a0 com funcionen les lents convergents, presents en les c\u00e0meres de fotos i en els nostres propis ulls. A m\u00e9s, ens hem preguntat: Per qu\u00e8 els nostres ulls s\u00f3n capa\u00e7os d\u2019enfocar els objectes?
\nLa caixa d\u2019observaci\u00f3 que hem constru\u00eft t\u00e9 una lent fixa i una dist\u00e0ncia focal fixa; per tant, per poder enfocar els objectes, nom\u00e9s podem variar la dist\u00e0ncia de l\u2019objecte a la lent. En els nostres ulls, la dist\u00e0ncia focal (del cristal\u00b7l\u00ed a la retina) \u00e9s fixa, no podem variar-la. Per\u00f2 els nostres ulls s\u00f3n capa\u00e7os d\u2019enfocar els objectes encara que estiguin a dist\u00e0ncies diferents: per aix\u00f2, el que fan variar \u00e9s la seva lent, \u00e9s a dir, el cristal\u00b7l\u00ed. Aix\u00f2 \u00e9s gr\u00e0cies al m\u00fascul ciliar, un m\u00fascul capa\u00e7 d\u2019estirar o relaxar el cristal\u00b7l\u00ed, permetent que els raigs de llum que passen per ell convergeixin de forma correcta a la retina segons si l\u2019objecte est\u00e0 m\u00e9s a prop o m\u00e9s lluny.<\/p>\n

Cal dir que els nostres ulls s\u00f3n unes de les m\u00e0quines m\u00e9s complexes i sofisticades dissenyades per la natura!!<\/p>\n
